I'd love to be able to participate, but my employer requires that a game jam post terms explicitly permitting entrants to retain ownership of their submissions.
Sample terms are listed here: https://opensource.google/docs/hackathons/#modelterms, although the important bit is just to explicitly define ownership of submissions.
Treat this as low priority, I often can't put aside the free time to jam anyway. I'd love to be able to put together a submission if the stars align.
Thanks,
